[PATCH v2 1/4] perf: Add a 'percore' event qualifier

Add a 'percore' event qualifier, like cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for both hardware threads in a core. We can already do this with --per-core, but it's often useful to do this together with other metrics that are collected per hardware thread. So we need to supp
